CORE=BOX.

SPECIFICATION forming part of Letters Patent No. 292,102, dated January 15, 1824 Application lili-d September l, 1883. (No model.)

Be it known that I, Plinio Covfrrc, of Seneca Falls, in the county of Seneca, in thc State of New York, have invented new and useful improvements in Core-Boxes, of which thc following, taken in connection iviththe accompanying drawings, is a full, clear, and exact description.

This invent-ion relates to the construction of cores required in casting elbows, Ts, angles, offsets, and analogous iittings forvsteam and Water pipes; and it consists in certain novel,

simple, and efiective devices for insuring the proper disposition of the axis of the core in relation to the ofthe pipes to be connected with the casting, so that when said parts are united they shall normally stand in their reu quired relative angle or position, all as hereinafter more fully described and specifically set forth in the claims.

In the annexed drawings, Figure l is a plan view of my invention in position ready for forming the core, the arbors of the core being represented by dotted lines. Fig. 2 is a plan view land longitudinal section of the plate by which the core-box is lifted out of its inclosing-case. Fig. 3 is a vertical transverse section on line a a', Fig. l. Fig. is a transverse section on line y y, with the arbors of the core shown, by full lines. Fig. 5 is a sectional view on the same line with the core-box and corearbors removed. Fig. 6 shows vertical transverse sections of the core complete and of the core-box removed theref'rom. Fig. 7 isaperspective view of the core removed from the core-box. Fig. S is an isometric view of the core-box, and Fig. 9 is an isometric view of the arborswhich are to occupy the center of the core.

Similar letters of reference indicate corresponding parts.

C represents a core-box for forming the core D ofa cross-pipe coupling, said coresbox being formed in detachable sections, illustrated in Fig. 8 or" the drawings, the line 0f division varying according to the style of casting to be made, said core-box having two cylindrical cavities ofthe size of the channels re quired in the casting, Which cavities intersect each other at the center, and in this case at right angles.

B is a bed-plate upon which to set the corebox during the process of forming the core, and H El denote heads or cheek-pieces secured to the bed-plate in any suitable manner, and frml y emln'acing opposite sides or" the corebox. The inner face of the cheek-pieces is provided with vertical flanges or ribs a a, which serve to guide the core-box Whenintroducing it into and removing it from its sustaining-case formed by the parts B. H, and H, so as to prevent disturbance of the vertical arbor A from its true axial position in the core during the operation of lifting the core-box out from between the cheekpieces H H and off the vertical bolt b. From the bed-plate projects upward a stud-pin or bolt, ll, which stands in range with the vertical axis of the cere-box, and on this bolt slides a plate, E, provided with an aperture, e, for the passage 7o of the said bolt, said plate being fitted between the cheek-pieces H ll, and adapted to rest on the bed-plate B, and having shoulders d d abutting against the guide-ribs a c, so as to be guided in its movement to and from the baseplate B. The ends ofthe plate E are provided with extensions fj', forming handles by which to manipulate said plate. The cheek-pieces H H are each provided with a transverse channel or eye, c, 'in which a bolt, 8o l, slides, in range with the horizontal or trans- 'verse axis of the core-box, the bolts being neatly fitted in their channels, so as to firmly sustain them in the aforesaid range.

A A denote arbors designed to be secured true in the axis of the core, so that, while forming a tie and brace for the same, they at the same time shall infallibly indicate the exact center or axis of the core and furnish convenient means of setting the core in its requisite position in the mold. Said arbors .are tubular .or hollow, and fitted to receivein their ends the hereinbefore-described bolts b I; and b', which, when introduced in the arbors, serve to firmly sustain the same in its position. The outer ends of the arbors I prefer to form with a flare or external enlargement, s, for the purpose of obtaining a more secure hold on the exterior of the core, and reenforc ing the same, and also affording the proper bearing for other cores that may be required to be connected therewith.

The described arbors may either consist of 011e piece, asillustrated in Fig. 9 of the drawings, or be formed in sections, as indicated by dotted lines in said figure, as may be found expedient.

The operation of forming a core by my improved appliances is as follows: The sliding bolts b I) being withdrawn, the plate E is slipped onto the vertical bolt b and passed down onto the bed-plate B. Then the arbors A A are placed in the core-box, and while inserting the latter between the cheeks H H the vertical branch of the arbors is slipped onto the vertical bolt b, and then the sliding bolts b b are pushed into the horizontal branches of the arbors A. The core-box is so fitted between the cheek-pieces H H and its guideribs a a that the bolts b b and b are in perfect range with the several axes of the core t0 be formed. After the core-box and its arbors are secured in the aforesaid position, the coreboX is filled solidly in lthe usual manner, and when this is accomplished the bolts b b are to be withdrawn. Then, by taking hold of the handles or extensions f of the plate E, said plate, together with the core-box, can belifted out from between the cheeks H H and 'off from the bolt b. The core-box may then be removed in sections from the core, and the latter is then ready to be subjected to the usual baking process.

It is obvious that the form of the case B H H, which supports the core-box, can be modified, andthe arbors A A disposed at different angles and positions in relation to each other, and the bolts b b b arranged correspondingly to adapt the apparatus for forming cores for Ts and branches and offsets of different angles required in water and steam fittings.

Having described my invention, what I claim is l. In combination with a core-box, a case embracing the same, arbors in the cavities of the core-box, and mea-ns, substantially as described, for sustaining the arbors, as set forth.

2. In combination with a core-box, a ease embracing the same, bolts projecting from the case to the axes of the core-cox, and an arbor or arbors sustained in the core-box by thebolts, and removable from the bolts to allow the coreboX to be removed from its embracing-case, substantially as and for the purpose set forth.

3. In combination with a core-box, a case embracing the same, and a tubular arbor sustained in the axes of the core-box by bolts sliding through the walls of the case and entering the central cavity of the arbor, substantially as described and shown.

4. In combination with a core-box, a sustaining case consisting of a bed-plate, and cheek-pieces attached to the bed-plate, adapted to receive between them the core box, channels through the cheek-pieces in range with the axes ofthe core-box, bolts sliding in said channels, and an arbor sustained in the core-box by the sliding bolts, substantially as described and shown.

5. In combination with a corefbox, a case embracing the sides and bottom of said box, a stud-pin or bolt projecting from the bed of the case into the vertical axes of the core-box, a removable plate extended across the bed ot' the case,and provided with a passage for the aforesaid bolt, boltssliding through the sides of the case in range with the horizontal or lateral axes of the core-box, and tubular arbors sustained in the core-box by the bolts entering the same,substantially as specified and shown.

6. In combination with a core-box, the bed B, fixed bolt b,cheeks H, provided with guides aand channels c, plate E, provided with the eye e and with the shoulders d and extensions f, bolts b b, sliding in channels c c, and the tubular arbors A, adapted to receive in them the aforesaid bolts, all constructed, combined, and operating substantially in the manner shown and set forth. v

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in thc county of Onondaga, in the State of New York, this 25th day of August, 1883.
